Dual 3 MHz, 600 mA Buck Regulator with 150 mA LDO

Product Details

The ADP5022 is a micro power management unit (micro PMU) that combines two high performance buck regulators and a low dropout regulator (LDO) in a tiny 16-ball 2.08 mm × 2.08 mm WLCSP to meet demanding performance and board space requirements.

The high switching frequency of the buck regulators enables tiny multilayer external components and minimizes the board space required. When the MODE pin is set high, the buck regulators operate in forced PWM mode. When the MODE pin is set low, the buck regulators automatically switch operating modes depending on the load current level. At higher output loads, the buck regulators operate in PWM mode. When the load current falls below a predefined threshold, the regulators operate in power save mode (PSM), improving the light-load efficiency.

The two bucks operate out-of-phase to reduce the input capacitor requirement and noise.

The low quiescent current, low dropout voltage, and wide input voltage range of the ADP5022 LDO extends the battery life of portable devices. The LDO maintains power supply rejection greater than 60 dB for frequencies as high as 10 kHz while operating with a low headroom voltage.

Each regulator in the ADP5022 has a dedicated, independent enable pin. A high voltage level applied to the enable pin activates the respective regulator. The default output voltages are factory programmable and can be set to a wide range of options.
